Has passed the test in a half-marathon.

No better way to attach a starting number. The Fixpoints make their name. In a half marathon they have not moved a millimeter. The attachment of the start number and I did not feel, as described by some other reviewers, as tricky. If you have to correct, that's better than certainly Nadelen. The weight you do not feel well while running. Finally, no more holes in jackets and shirts.
